UMO+ Hot End Isolator Tube Stuck in PEEK

Recommended Posts

Posted · UMO+ Hot End Isolator Tube Stuck in PEEK


I was assembling my UMO+, and I realized that I had screwed the hot end isolator tube into the wrong side of the peek, and now I can't unscrew it (I tried wrenches, bare hands, gloves, tried until i got bloody fingers). Does anybody have any tips for this? It's kinda sad, cuz if I can't fix it, I'm kinda screwed (and my local reseller doesn't sell a UMO+ hotend pack).

Thanks in advance!

    Try freeze spray on the metal only for a long 20 seconds and then grip with rubber sheet or rubber gloves. The cold will make the metal shrink faster than the PEEK part.

    What I do to take it out its:

    Assemble the nozzle while hot like if you where going to use it. Then unscrew the peek. It comes out very easy if the nozzle pressure it's 'on'. I broke 4 barrels or more before finding out :D

    Upss I get it. You can't do that... Then do what gr5 says indeed.

    Hey Nerdwarrior, I have the same problem, how did you solved it?



    It's been years and I honestly don't remember. I'm guessing I went with either gr5 or neotko's tip. To freeze you can take some canned air and spray it while inverted (comes out as refrigerant). For heating, I wouldn't recommend fire, but you could maybe try hot water or attaching the block/heater/thermistor and heating it up. 

    Hope that helps!

    Thank you! I´ ve tried to attached it to the block and and hot water but it´´´  s stucked. In my case the brass went through all the peek so is harder to heat the hole brass part. Will try the freeze method. thank you for your reply!

      • UltiMaker Cura 5.3 stable released
        In this stable release, Cura 5.3 achieves yet another huge leap forward in 3D printing thanks to material interlocking! As well as introducing an expanded recommended print settings menu and lots of print quality improvements. Not to mention, a whole bunch of new printer profiles for non-UltiMaker printers!
          • Thanks

      • Here it is. The new UltiMaker S7
        The UltiMaker S7 is built on the success of the UltiMaker S5 and its design decisions were heavily based on feedback from customers.
        So what’s new?
        The obvious change is the S7’s height. It now includes an integrated Air Manager. This filters the exhaust air of every print and also improves build temperature stability. To further enclose the build chamber the S7 only has one magnetically latched door.
        The build stack has also been completely redesigned. A PEI-coated flexible steel build plate makes a big difference to productivity. Not only do you not need tools to pop a printed part off. But we also don’t recommend using or adhesion structures for UltiMaker materials (except PC, because...it’s PC). Along with that, 4 pins and 25 magnets make it easy to replace the flex plate perfectly – even with one hand.
        The re-engineered print head has an inductive sensor which reduces noise when probing the build plate. This effectively makes it much harder to not achieve a perfect first layer, improving overall print success. We also reversed the front fan direction (fewer plastic hairs, less maintenance), made the print core door magnets stronger, and add a sensor that helps avoid flooding.

        The UltiMaker S7 also includes quality of life improvements:
        Reliable bed tilt compensation (no more thumbscrews) 2.4 and 5 GHz Wi-Fi A 1080p camera (mounted higher for a better view) Compatibility with 280+ Marketplace materials Compatibility with S5 project files (no reslicing needed) And a whole lot more  
        Curious to see the S7 in action?
        We’re hosting a free tech demo on February 7.
        It will be live and you can ask any questions to our CTO, Miguel Calvo.

      • UltiMaker Cura Alpha 🎄 Tree Support Spotlight 🎄
        Are you a fan of tree support, but dislike the removal process and the amount of filament it uses? Then we would like to invite you to try this special release of UltiMaker Cura. Brought to you by our special community contributor @thomasrahm
        We generated a special version of Cura 5.2 called 5.3.0 Alpha + Xmas. The only changes we introduced compared to UltiMaker Cura 5.2.1 are those which are needed for the new supports. So keep in mind, this is not a sneak peek for Cura 5.3 (there are some really cool new features coming up) but a spotlight release highlighting this new version of tree supports.
